This invention relates to attachments for intakes of gasoline enginesand is particularly related to devices for saving fuel.

In the vaporization and mixing of gasoline with air to form a mixture,it has been found that a complete vaporization of the gasoline andmixture with air will give a better explosion if a small amount ofmoisture is present. The present invention provides a means for bringingabout these results.

The primary object of this invention is the provision of an improvedfuel saver.

Another object of the invention is the provision of an improved fuelsaver having a heating unit to assist in completely gasifying thegasoline in the air and a moisture feeding device to supply a watercontent to the mixture.

Another and further object of the invention is the provision of animproved fuel saver having a heating unit, a means for supplyingmoisture to the mixture and a means for causing the mechanical mixing ofthe gas mixture. 2

Other and further objects of the invention will be apparentto thoseskilled in the art from a readingof the completespecification andclaims.

In the drawing wherein I have illustrated an embodiment of my invention,a

Figure 1 is a top view of my invention. Figure 2 is an end view.

35 Referring particularly to Figure 3 where a cross'section of the partsis illustrated, 10

designates the main body of the device having a'ohamber 11. The chamber11 has a clo sure member 12 secured in place by screws 13.

A gasket member 12 is provided to make a tight joint.

The top and bottom surfaces of the main body member 10 are planesurfaces and are adapted to fit the under surface of the intake manifoldand theupper surface of the carburetor respectively. The main body 10 isconstructed so as to be capable of insertion between the two normallycoacting surfaces of the intake manifold and the carburetor. The opening14 registers with the opening in the manifold and the opening 15registers with the opening in the carburetor. The ears 16, with holes 16are provided at the upper face of the body portion 10 to secure thedevice to the manifold and the ears 17 with holes 17? are provided atthe bottom to register with and to be secured to the carburetor.

Vithin the chamber 11 and secured to one wall as by the bolts 18, is ascreen 19. Ex-

tending through the wall of the main bodymember 10 and below the screen19, is'a heating unit 20. This heating unit 20 has a heat-- ing wire 21which extends to terminals 22 which in turn are mounted on theinsulating block 23. The wire 21 is mounted on a mica 1 sheet and thewhole is embedded in the clay.

The block 3 is secured to the main body member 10 by the screws 2 1. Anon-conducting gasket 25 seals the opening in the main body member 10,through which the heating unit 20 passes.

Between the screen 19 and the heatin unit 20 is a filling of suitablefibrous material. such as asbestos as at 25. v

An opening 26 through the wall of the main body 10 receives the threadedend of a water supply pipe 27. Within the pipe 27 is a fibrous materialas a continuation of the material 25. At the end of the pipe 27 is asuitable Water reservoir 28 to supply the water to moisten the mixture.An opening 29 is provided for filling the reservoir 28.

In order to assist in the mixing operation .I provide a hirligig havinga freely rotating shaft 30 between the walls of the main body member 10.-This shaft carries curved blades 31 which are so shaped as to hold thecurrent of gas and air mixture so as to turn.

This turning action assists in the mixing operation and helps deflectthe mixture toward the screen to absorb the moisture.

In the wall of the main body member 10 and communicating from theoutside air to i the moisture laden asbestos-pad 25 is an opening 32 tosupply a small amount of air to assist in evaporation of the'moisture inthe asbestos pad 25.

In operating, the rarification of the air in the exhaust manifold abovethe opening 14,

causes the atmospheric pressure below the L carburetor to cause air torush through the carburetor and through the opening 15. This air isladen with gasoline particles some of which may be in the form of minutedrops suspended in the air. This more or less raW. mixture first strikesthe heating unit 20 Which is being heated by passing electricity throughthe wire 21. The heat here absorbed causes complete gasification of theparticles of gasoline. The mixture then passes around the end (left inFigure 3) of the heating unit 20 and moves toward the opening 14 on theWay to the intake manifold.

This mixture passes the Whirligig and moves the blades 31 causing theWhirligig to turn. This action tends to further mix the gases which makeup the mixture. At the same time, the partial vacuum in the chamber 11,causes atmospheric pressure on the outside to force a small amount ofair through the opening T his air strikes the asbestos 25 and evaporatesthe moisture therein.

In addition, the Water falling on or in close proximity to the heaterunit 20, is further assisted in its evaporation. The evaporated moisturepasses through the screen and into the mixture then in the chamber 11.After the thorough mixing in the chamber 11, the mixture With the air,gasified gasoline and evaporated Water passes into the intake manifoldand is used as a power fuel.

I have found my fuel saver to be particularly effective in causing acomplete mixture between the gasified gasoline, air and Water vaporwhich results in a saving of gasoline.

While I have illustrated and described in detail an embodiment of myinvention, 1 desire to have it understood that the showing anddescription are merely illustrative, that I do not limit myself to thedetails of such showing and description and that modifications andchanges'may be made Without departing from the spirit of the inventionand within the scope of the appended claims.

Having described my invention What I claim and desire to secure byLetters Patent is 1. A fuel saver for gasoline engines comprising a bodyportion, a carburetor connection, an intake connection and a heaterdirectly in the path of travel between the two connections so that'thegases impinge upon the heater.

2. A fuel saver for gasoline engines comprising a body portion, acarburetor connection, an intake connection, a heater directly in thepath of travel of the mixture carburetor from the carburetor and meansfor delivering Water moisture to the heater.
